A kind of mechanical clamping device
Technical field
This practicality belongs to deliverance apparatus component technology field, is specifically related to a kind of mechanical clamping device simple in structure that is used for.
Background technology
Pumping irrigation well is eaten the people, the incident of hurting sb.'s feelings takes place repeatedly, makes many families experience misfortunes, and serious threat peasant's the security of the lives and property has influenced rural economic development.When falling the well accident, it generally is the firefighters relief of going into the well, also have and use Underwell rescue device to succour, the pumping irrigation well well head is little, after deliverance apparatus puts down, be difficult to can hold again a people and go down to assist relief, and during the manipulator clamping person down the well of deliverance apparatus, may be owing to clamping stable inadequately, or manipulator unclamps and causes the rescue failure in the rescue process.Therefore, a kind of mechanical clamping device that need not manual operation of design seems particularly important.
Summary of the invention
At the above-mentioned problems in the prior art, it is a kind of simple in structure that the purpose that the utility model provides is to provide, easy to use and mechanical clamping device that security performance is good.
Described a kind of mechanical clamping device, it is characterized in that comprising finger, arm support, tooth bar support, connecting rod, slide block, motor and tooth bar, described arm support, tooth bar support are fixedlyed connected with motor respectively, described tooth bar support is equipped with in the cavity that arm support is provided with, be used for fixing the tooth bar, described connecting rod one end is connected with finger, and the other end is connected with slide block, described slide block is threaded with the tooth bar, and described finger middle part is articulated and connected on arm support.
Described a kind of mechanical clamping device is characterized in that described slide block is a double-vane shape structure, and the middle part is equipped with tapped through hole, and described tooth bar is connected in the through hole by threaded engagement.
Described a kind of mechanical clamping device is characterized in that described finger is a S shape structure.
Above-mentioned a kind of mechanical clamping device, it is characterized in that comprising finger, arm support, tooth bar support, connecting rod, slide block, motor and tooth bar, described arm support, tooth bar support are fixedlyed connected with motor respectively, described tooth bar support is equipped with in the cavity that arm support is provided with, be used for fixing the tooth bar, described connecting rod one end is connected with finger, and the other end is connected with slide block, described slide block is threaded with the tooth bar, and described finger middle part is articulated and connected on arm support.The utility model is by adopting above-mentioned technology, by the rotation of Electric Machine Control tooth bar, drive slide block and slide up and down, thereby control opening and clamping of finger, simple in structure, easy to use and security performance is good, cooperate Underwell rescue device to be used when being suitable for downhole rescuing.
Description of drawings
Fig. 1 structural representation of the present utility model.
Among the figure: comprise the 1-motor, 2-slide block, 3-connecting rod, 4-finger, 5-arm support, 6-tooth bar, 7-tooth bar support.
The specific embodiment
Below in conjunction with Figure of description the utility model is further described:
As Figure 1-3, a kind of mechanical clamping device, comprise finger 4, arm support 5) tooth bar support 7, connecting rod 3, slide block 2, motor 1 and tooth bar 6, described arm support 5, tooth bar support 7 is fixedlyed connected with motor 1 respectively, described tooth bar support 7 is equipped with in the cavity that arm support 5 is provided with, be used for fixing tooth bar 6, described connecting rod 3 one ends are connected with finger 4, the other end is connected with slide block 2, described slide block 2 is threaded with tooth bar 6, described slide block 2 is a double-vane shape structure, and the middle part is equipped with tapped through hole, and described tooth bar 6 is connected in the through hole by threaded engagement.Described finger 4 middle parts are articulated and connected on arm support 5, and described finger 4 is a S shape structure, and S shape two radians are different, and little radian one side head is connected with connecting rod 3, and big arc one side is used for the clamping operation.
During work, open motor 1, the rotation of motor 1 drives 6 rotations of tooth bar, the slide block 2 that is threaded with tooth bar 6 can slide up and down, when upwards sliding, slide block 2 drivening rod 3 one ends successively moves upward, the other end of connecting rod 3 drives finger 4 upper ends that are articulated and connected with it and inwardly moves, and points 4 lower ends and opens, and carries out clamping people's arm, after clamping is stable, 6 motions in the other direction of motor 1 control tooth bar, slide block 2 is when lower slider, and slide block 2 drivening rod 3 one ends successively moves downward, the other end of connecting rod 3 drives finger 4 upper ends that are articulated and connected with it and outwards moves, after pointing 4 lower ends and slowly clamping, cooperate deliverance apparatus that the person down the well is rescued, the utility model is simple in structure, easy to use and security performance good, cooperate Underwell rescue device to be used when being suitable for downhole rescuing.
